Java 9: Building Robust Modular Applications

By: Dr. Edward Lavieri, Peter Verhas, Jason Lee

Overview of this book

Java 9 and its new features add to the richness of the language; Java is one of the languages most used by developers to build robust software applications. Java 9 comes with a special emphasis on modularity with its integration with Jigsaw. This course is your one-stop guide to mastering the language. You'll be provided with an overview and explanation of the new features introduced in Java 9 and the importance of the new APIs and enhancements. Some new features of Java 9 are ground-breaking; if you are an experienced programmer, you will be able to make your enterprise applications leaner by learning these new features. You'll be provided with practical guidance in applying your newly acquired knowledge of Java 9 and further information on future developments of the Java platform. This course will improve your productivity, making your applications faster. Next, you'll go on to implement everything you've learned by building 10 cool projects. You will learn to build an email filter that separates spam messages from all your inboxes, a social media aggregator app that will help you efficiently track various feeds, and a microservice for a client/server note application, to name just a few. By the end of this course, you will be well acquainted with Java 9 features and able to build your own applications and projects. This Learning Path contains the best content from the following two recently published Packt products: • Mastering Java 9 • Java 9 Programming Blueprints

Just like that, once again, our application is finished. We've covered quite a bit in this chapter. We started by learning a little bit about the history and technical details of several email protocols (SMTP, POP3, and IMAP4), then learned how to interact with services based on those using the JavaMail API. In the process of doing so, we discovered the Jackson JSON Parser and used it to marshal and unmarshal POJOs to and from the disk. We used the ControlsFX class, BeanPathAdapter, to bind non-JavaFX-aware POJOs to JavaFX controls, and the Quartz Job Scheduling Library to execute code on a schedule. Finally, we wrapped up our application using the Java Service Wrapper to create installation artifacts.

We're left with what I hope is an application that is both interesting and helpful. There are several ways to improve on it, of course, if you feel so motivated. The account/rule data structure could be extended to allow defining global rules that are shared across accounts. The GUI...
